Directed by Andreas Nilsson, the new "Birthday Song" video from 2 Chainz and Kanye West is all over the place. We see clowns getting beat up, we see plenty of ass, we see midgets running around, and we see Kanye on one extremely weird bicycle. Or is it a tricycle? EIther way, it has a cake attached to the back that contains a ... yep, you guessed it, big booty hoe. Enjoy the profuse amounts of ratchetness below.
